The example in this article describes the JS method of placing the mouse on a link to display scrolling text. Share it with everyone for your reference, the details are as follows:

<div id="tooltip2" style="position:absolute;visibility:hidden;clip:rect(0 150 50 0);width:150px;background-color:seashell">
<layer name="nstip" width=1000px bgColor="seashell"></layer>
</div>
<SCRIPT language="JavaScript">
<!--
if (!document.layers&&!document.all)
event="test"
function showtip2(current,e,text){
if (document.all&&document.readyState=="complete"){
document.all.tooltip2.innerHTML='<marquee style="border:1px solid black">'+text+'</marquee>'
document.all.tooltip2.style.pixelLeft=event.clientX+document.body.scrollLeft+10
document.all.tooltip2.style.pixelTop=event.clientY+document.body.scrollTop+10
document.all.tooltip2.style.visibility="visible"
}
else if (document.layers){
document.tooltip2.document.nstip.document.write('<b>'+text+'</b>')
document.tooltip2.document.nstip.document.close()
document.tooltip2.document.nstip.left=0
currentscroll=setInterval("scrolltip()",100)
document.tooltip2.left=e.pageX+10
document.tooltip2.top=e.pageY+10
document.tooltip2.visibility="show"
}
}
function hidetip2(){
if (document.all)
document.all.tooltip2.style.visibility="hidden"
else if (document.layers){
clearInterval(currentscroll)
document.tooltip2.visibility="hidden"
}
}
function scrolltip(){
if (document.tooltip2.document.nstip.left>=-document.tooltip2.document.nstip.document.width)
document.tooltip2.document.nstip.left-=5
else
document.tooltip2.document.nstip.left=150
}
//--> 
</SCRIPT>
<a href=# onMouseOver="showtip2(this,event,'看到了吧？')" onMouseOut="hidetip2()">把鼠标放上来试试</a>
